How to Improve Your Site’s Performance When Using GIFs
Posted by Web_Perfectionist
The GIF (Graphics Interchange Format) format was originally developed in 1987. Debuted by Steve Wilhite of Compuserve, GIFs improved on the black-and-white images in use during that time by allowing the use of 256 colors while maintaining a compressed format that could still be loaded by those utilizing slow modems. Furthermore, web developers and designers could create animations via timed delays. And to this day, little has changed regarding GIFs.
Due to its simplicity, the widespread support for this format, and the ease with which it can be used to stream video clips, the GIF format is the oldest file format still commonly used today. This frame animation feature of GIFs ensures that the format remains popular, despite the rise of JPEG and PNG images.
In spite of their popularity and ubiquitousness on the Internet (especially with regards to animated GIFs), GIFs are not the most performant of image options. If you are using GIFs on your sites, it’s important that you take care to optimize your GIFs so that they do not create too much overhead.
This article will cover ways to optimize your GIFs, both static and animated, and will offer an excellent alternative you can use to eliminate the page bloat resulting from use of GIFs as animation.
Why should you optimize your GIFs?
Performance matters when it comes to designing your web pages, and GIFs are not the most performant of image options. While they are excellent for capturing your user’s attention and are universally liked for providing short bursts of information in an entertaining way, GIFs were not designed for animation (despite them being commonly used for such). As such, usage of GIFs leads to heavy page weights and poor user experiences resulting from slow page load speeds.
How to improve the performance of your site while using GIFs
In this section, we’ll cover several ways you can improve the performance of your site with regards to using GIFs. We’ll first dig into ways to handle static GIFs, and we’ll end by discussing ways to minimize the overhead resulting from animated GIFs.
There are two methods for compressing images:
One of the primary methods for optimizing GIFs is to compress them. There are two methods of compression that are commonly used:
- Lossy compression: Lossy compression removes some of the data from the original file, resulting in an image with a reduced file size. However, every time you save the file after compression, the quality of the graphic degrades somewhat, which can result in a fuzzy, pixelated image over time.
- Lossless compression: Lossless compression preserves all of the data from the original file, which means that the compressed file can be uncompressed to gain the original file. While your file size remains larger than if you had used lossy compression, your image’s quality does not degrade over time.
Later on in this post, we’ll cover the impact of both types of optimization on GIFs.
